Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain Eukarya.
      • Choanoflagellata 0 questions
      • Cryptophyta 0 questions A division (some say phylum or class) of the ALGAE, characterized by biflagellated cells and found in both freshwater and marine environments. Pigmentation varies but only one CHLOROPLAST is present. Unique structures include a nucleomorph and ejectosomes.
      • Diplomonadida 0 questions An order of protozoa characterized by the presence of one or two karyomastigonts and either two-fold rotational or mirror symmetry.
      • Euglenozoa 0 questions
      • Champignons 2 questions A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
      • Haptophyta 0 questions
      • Mésomycétozoaires 0 questions A class of parasitic and saprophytic microorganisms whose origins can be traced near the animal-fungal divergence. Members of the class are typically pathogens of FISHES, but there are exceptions. There are two recognized orders: Icthyophonida and Dermocystida.

          • Dientamoeba 0 questions Genre de petits protozoaires qui sont caractérisés par la prépondérance de formes binuclées par rapport aux formes mononuclées, la présence de plusieurs granules distincts au niveau du caryosome, et l'absence d'étape kystique. C'est un parasite du grand intestin des humains et de certains singes.
          • Trichomonas 0 questions A genus of parasitic flagellate protozoans distinguished by the presence of four anterior flagella, an undulating membrane, and a trailing flagellum.
          • Tritrichomonas 0 questions A genus of flagellate protozoans possessing three long anterior flagella.

      • Plantes 1 question Multicellular, eukaryotic life forms of the kingdom Plantae. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alteration of haploid and diploid generations.

    • Archéobactéries 0 questions One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.
